*accurate*?

My thinking is no, correlation cannot tell you if the estimated age is accurate, but I'm not 100%.

Additional info: the estimated ages are obtained by following a method that examines features of the skeleton.

Thanks in advance!

I agree that correlation can't tell you that. After all, there would be a perfect correlation of r=1.0 between the following pairs of estimated age/actual age: 3/83, 4/84, 5/85, 6/86, 7/87. (But as you can see the guesses are all 80 years off the mark).

I feel like either a standard deviation of the difference scores or a mean absolute difference score would be a pretty good metric of accuracy in this case. But I have no idea if either of those are actually done in cases like this.

So in terms of approaches that*do* work, I'll let others who know what they're talking about more than me point you in the best direction.

Not familiar with Youden plot. I know Youden Index, but that is for a binary by continuous comparison (I least I thought).
